Self-affirmation is a method for maintaining or restoring one’s global positive self-integrity from threats, which require affirming some important aspects of the self that is unrelated to the threaten domain. It can be done by accomplishing a value scale, describing an important value, engaging in activities that remind them of “who they are”. The participants who affirmed were more openness and objective to the threaten self-identity or group-identity information, promoting personal well-being. These effects may be the result of central route processing on the persuasive information. There is ample opportunity to develop the effect of self-affirmation in the domain of the most important value had been threatened, the interaction of multiple mechanisms for self-affirmation, the differences between self-affirmation and group-affirmation, and the cross-cultural differences in the effect of self- or group-affirmation.
